How to protect credit card & ID numbers

Hi to everyone,

I recently installed CIS Pro 2011 on XP Pro SP3, I would like to protect my credit card, ID and other personal information numbers. I think also to do the same with some application serials including Windows & Office. Can someone tell me how I can do that?

Thanks in advance.

two suggestions:

  1. keepass password manager (freeware). choose a good password for it, make all the possible settings (example: increase the loop time for each password try. brute force will be taking looong :smiley: )

  2. air gap: no one can hack a piece of paper hidden in a safe place :wink:
